[Pooling] iOS Developer (Software)

We are looking for an iOS Developer (full-stack engineer) with deep iOS expertise who builds cross-platform mobile applications using React Native while maintaining strong native iOS skills for platform-specific optimizations. Beyond mobile, this role contributes to backend services (NestJS/Python) that power mobile features and builds web features when capacity allows. The individual owns the iOS experience end-to-end: from API integration to App Store deployment, performance optimization, and platform-specific native module development.

Responsibilities

iOS & React Native Development (Primary Focus)

• Build and maintain the iOS mobile application using React Native with TypeScript.
• Develop platform-specific native modules (Swift/Objective-C) when React Native abstractions are insufficient.
• Optimize iOS performance – memory management, battery optimization, app launch time, smooth animations.
• Manage App Store deployment pipeline – builds, code signing, TestFlight, App Store Review process, phased releases.
• Implement iOS-specific features: push notifications (APNs), deep linking, HealthKit integration, permissions.
• Debug iOS-specific issues using Xcode, Instruments, Flipper, and React Native debugging tools.
• Ensure consistent UX between iOS and Android implementations.

Full-Stack Backend Contributions

• Build and maintain NestJS API endpoints that power mobile features – push notification services (APNs), device management, sync APIs.
• Contribute to Python-based backend services for data processing, file handling, and mobile-specific workflows.
• Design mobile-optimized API responses – pagination, data compression, offline-first sync patterns.
• Write database queries and manage mobile-related data schemas in PostgreSQL and MongoDB.

Web Frontend Contributions

• Contribute to React/TypeScript web features when sprint capacity allows.
• Share components and business logic between React Native mobile and React web where applicable.
• Participate in code reviews across mobile, backend, and web PRs.
• Use AI-assisted development tools to accelerate development and solve complex platform issues.

Qualifications

• 3–5 years of mobile development with at least 2 years React Native + iOS experience.
• Strong iOS fundamentals – UIKit/SwiftUI concepts, native modules, platform APIs, Instruments profiling.
• React Native expertise – navigation, state management, native bridge, Expo ecosystem.
• TypeScript proficiency – type-safe mobile development, shared type definitions.
• NestJS / Node.js competency – can build and maintain backend APIs for mobile features.
• Python basics – scripting, data processing, simple API development.
• App Store deployment – end-to-end submission, TestFlight, App Review guidelines, code signing.
• Database skills – PostgreSQL, MongoDB, and mobile local storage (Core Data/SQLite).
• AI tool proficiency – uses AI coding assistants; understands LLM API basics.

Nice-to-Have

• Experience with Android development or Kotlin for cross-platform debugging.
• Knowledge of Core ML or on-device ML frameworks.
• Experience with HealthKit or health-related iOS frameworks.
• Familiarity with CI/CD for mobile (Fastlane, GitHub Actions).
